omniauth-openshift

This is an Omniauth stategy for authenticating users against OpenShift, useful when writing applications for users of OpenShift (as opposed to users of apps deployed on OpenShift). For example, custom self-service monitoring, provisioning or similar capabilities.

gem install omniauth-openshift

To configure this provider you will need a couple things:

1. A list of scopes needed for OCP access
2. The public master url (site below)
3. The url for the deployed app with the full path that OpenShift should redirect the user to (redirect_uri below)
4. A client id and secret that are registered with OpenShift as an OAuthClient. An example is included below.

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :openshift, {
    scope: ['user:full', 'user:info'],
    response_type: :code,
    client_id: 'example-client',
    client_secret: 'super-secret',
    client_options: {
      redirect_uri: 'http://myapp.paas.example.com/auth/openshift/callback',
      site: 'https://master.example.com:8443/'
    }
  }
end

The following yaml can be used to register an oauth client with OpenShift.

apiVersion: v1
grantMethod: auto
kind: OAuthClient
metadata:
  name: example-client
redirectURIs:
- http://myapp.paas.example.com/auth/openshift/callback
secret: super-secret

Note that the name in the OAuthClient is the client_id for OmniAuth, and the secret is the client_secret. Additionally, redirect URIs must be identical.
